AC_CHECK_MEMBER is exactly what we need :)
however, for some reason, this patch did not work as expected. it
prevented AC_CHECK_LIB from working and adding -lfetch
I reworked the patch as follow :
diff --git a/configure.ac b/configure.ac
index b2164b9..e0d0687 100644
--- a/configure.ac
+++ b/configure.ac
@@ -144,6 +144,11 @@ if test "x$internaldownload" = "xyes" ; then
# Check for a download library if it was actually requested
AC_CHECK_LIB([fetch], [fetchParseURL], ,
AC_MSG_ERROR([libfetch is needed to compile with
internal download support]) )
+ # Check if libfetch supports conditional GET
+ # (version >=2.21, struct url has member last_modified)
+ AC_CHECK_MEMBER(struct url.last_modified, ,
+ AC_MSG_ERROR([libfetch must be version 2.21 or greater]),
+ [#include <fetch.h>] ),
else
AC_MSG_RESULT(no)
fi
Does it look fine to you? and do you know why yours did not work for me?
